Homogeneous multi-mission along-track Sea Level Anomalies, Wave and Wind (Level-2P) : implementation of Sentinel-6A/Jason-CS
Event: 2022 Ocean Surface Topography Science Team Meeting
Session: Application development for Operations
Presentation type: Poster
L2P products were reprocessed in 2021 [1][2][3]. They are easy to use homogenous along-track mono-mission products, providing as much as possible the same updated corrections and models for the altimeter missions, in order to facilitate inter-mission comparisons. The products contain the sea level anomaly as well as all the corrections used to compute it, wind and wave. A validity flag, enable users to discard data with spurious measurements. The sea level anomaly level 2P products are, among other uses, the input data for level 3 products and for the Global Mean Sea Level computation (an inter-mission bias is applied in order to have consistent time series since TOPEX/Poseidon).
We present here the implementation of the new Copernicus mission Sentinel-6A/Jason-CS, an international partnership between the U.S. and Europe. On the Jason orbit, Sentinel-6A/Jason-CS will ensure continuity of sea level observations into a fourth decade.
In the frame of the SALP [4] project supported by CNES [5] and of the Sentinel Marine Altimetry L2P-L3 Service [6] level 2P data of sea level anomalies product and wind/wave product are available to users in delayed time on AVISO+ ( https://www.aviso.altimetry.fr/en/data/products/sea-surface-height-products/global/along-track-sea-level-anomalies-l2p.html ) for all the altimeter missions : TOPEX/Poseidon, Jason-1/2/3, ERS-1/2, Envisat, Saral/AltiKa, Sentinel-3A/B, GFO, Cryosat-2, HY-2A, HY-2B and soon Sentinel-6A/Jason-CS.
